“…In addition, the Pn under the SS treatment (low-soil water) in the longterm experiment was higher than that under the SS treatment in the short-term experiment. These indicate that moderate drought is beneficial for increasing the Pn of plants (Zhang et al, 2008), but these findings are not in accord with the research by Lamptey et al (2020), which may be related to differences in crop types and climate. Furthermore, the short-term SM treatment and the long-term SS treatment were more beneficial for improving the Pn of wheat, and the Tr of those treatments was also relatively higher, but, compared with the control, the Pn increased more significantly than Tr, which improved the LWUE and promoted the accumulation of dry matter (Shi et al, 2016).…”

“…When soil water availability is improved, the physiological characteristics of crops are also improved (Xiao et al, 2007;Lamptey et al, 2020). Subsoiling is more beneficial to the improvement of photosynthetic physiological characteristics of wheat (Yang et al, 2014b) and maize (Lamptey et al, 2020). Straw mulching can increase soil moisture and improve the leaf area index and the net photosynthetic rate of wheat (Zhang et al, 2010(Zhang et al, , 2019Yang et al, 2014b).…”

Water shortages and rainfall variability lead to a decrease in grain yield. Straw mulching (SM), subsoiling (S), and combined amendments (subsoiling + straw mulching, SS) are potential solutions for maintaining crop productivity and water resource sustainability. However, short- and long-term applications of these methods appear to result in different yield and water use efficiency outcomes. In this study, we, therefore, compared short- and long-term applications of SM, S, and SS, with a control. We analyzed field experimental data of wheat and maize cultivation with control (conventional tillage), SM, S, and SS treatments to assess the impact on yield and water use efficiency, resulting from short- and long-term applications of these practices. The results show that SS treatment led to higher soil water storage (SWS) compared with other treatments during the regreening, jointing, and booting stages of wheat, and the big bellmouth and filling stages of maize in the short- and long-term experiments. However, long-term SS treatment also led to higher SWS in the growth stage of wheat in 2015–2016 and in the growth stage of maize in 2015. Additionally, SS treatment was conducive to raising the net photosynthetic rate (Pn) and leaf water use efficiency (LWUE) of wheat compared with other treatments in 2015 and 2016. Conversely, Pn and LWUE of maize under S and SS treatments were higher (P < 0.05) compared with other treatments in the two studied years. Short-term treatment led to higher wheat yield compared with long term in 2014–2015 (ample rainfall) and of maize in 2016 (low rainfall). The yield of wheat under long-term S treatment in 2015 was 9625.-kg hm−2, which was the highest (P < 0.05) in 2 years, with a 17.7% increase compared with the control, followed by short-term S treatment. However, the water use efficiency (WUE) of wheat under long-term SS treatment in 2016 was the highest (P < 0.05) compared with other treatments. The yield of maize under SM and S treatments was higher than other treatments, whereas the WUE of maize under long-term SS treatment in 2016 was still the highest (P < 0.05). Our findings provide evidence that S and SS treatments improve both crop productivity and water resource sustainability, and long-term application resulted in higher productivity than short-term application.

“…Reduced soil disturbance with straw addition has been revealed to improve water infiltration (Kirkegaard et al, 2014), reduce water loss by limiting evaporation (Govaerts et al, 2006), and increase crop water use efficiency (Fan et al, 2012). According to Lamptey et al (2020), differences in soil water storage at different growth stages were mainly ascribed to different tillage systems (Table 3). From Table 3, tillage effect on soil water storage were more pronounced in the reduced tillage systems during the study years.…”

Water is one of the very important inputs necessary for the production of food crops hence, food security and rural livelihoods are essentially linked to the accessibility of water. Eighty percent of the world's global agricultural land area is under rain-fed; this contributes to 58% of the world's staple foods. In Sub-Sahara Africa (SSA), reliance on rain-fed agriculture is high with 97% of the moisture needs of crops fulfilled mainly by water stored in the soil through rainfall. Due to highly unpredictable and sporadic seasonal rainfalls in SSA, rainfall cannot meet the requirements for crop growth and development resulting in lower crop yields with consequent food insecurity. It is important that water in rain-fed agriculture is used efficiently and effectively through interventions that conserve soil water. Thus, water productivity under rain-fed agriculture must be enormously improved particularly in SSA where the climate is dry and over 90% of agricultural activities are rainfed. However, uncertainty in rainfall projections and magnitude makes rainfed crop production a real challenge. Therefore, water management through daily field activities (agronomic practices) is a critical constituent that needs to be adopted in the current challenge of rainfall variability, climate change and expected increase demand for food. This paper highlights potentials of some agronomic practices for improved soil water content. Agronomic practices such as crop selection, mulching, fertilization and soil tillage has the potential to improve soil water content for improved and sustainable crop production.

Soil compaction and resource competition are bottlenecks in the improvement of sugarcane productivity in intercropping systems. Fenlong tillage improves crop yields by alleviating soil compaction and ensuring water supply. Wide‐narrow rows are an effective solution for light competition. An efficient intercropping system with Fenlong tillage technology as the core needs to be constructed. A two‐cycle field study was conducted to investigate the effects of planting methods [sole ratoon sugarcane (S) and ratoon sugarcane‐soybean intercropping (I)] combined with tillage [conventional rotary tillage (RT), Fenlong tillage “145” mode (FL145)] on soil physical characteristics, photosynthesis, and growth of ratoon sugarcane, as well as crop yields. For the ratoon sugarcane, compared to RT‐I, FL145‐I decreased bulk density and increased porosity in the 0–40 cm soil layer. Root growth parameters were improved under FL145‐I in the 0–20 cm soil layer. FL145‐I positively affected the stomatal conductance, causing increases in the net photosynthetic and transpiration rates. The increased leaf area index, chlorophyll relative content, and photosynthesis under FL145‐I caused higher dry matter accumulation. The increased single stalk weight under FL145‐I resulted in 17.13%–22.55% higher stalk yield with similar quality. Intercropping under the wide‐narrow row planting pattern had no negative effects on the growth and stalk yield of ratoon sugarcane. For the soybean, compared to RT‐I, the increased 100‐seed weight under FL145‐I resulted in 11.14% higher seed yield with similar quality. Therefore, FL145‐I presents a promising and novel management practice for sustainably increasing ratoon sugarcane productivity in China.
